Corydalis ambigua is a tuberous early flowering east Asian flowering plant species. Its exact native range is obscure due to taxonomic confusion.[1] It is one of the sources of the drug tetrahydropalmatine.


Corydalis ambigua contains a variety of alkaloids including corynoline, acetylcorynoline d-corydalin, dl-tetrahydropalmatine, protopine, tetrahydrocoptisine, dl-tetrahydrocoptisine, d-corybulbine and allo-crytopine.[2][3][4][5]

Chemical derivatives of tetrahydroprotoberberines present in Corydalis ambigua have been studied as potential ways to increase pain tolerance and for treating drug addiction.[6] Further, they may represent a category of neurotransmitter stabilizers which have potential use in broad range of psychotic and neurological disorders.[6]
